Validation results of two benchmark FSI problems are illustrated, including dam-break flow through an elastic gate (Antoci et al.,2007) and free surface flow impacting on an elastic obstacle (Liao et al.,2015). The results obtained by improved MPS-FEM coupled method show good agreements...

.... In recent years, the mesh-free method MPS has gained popularity for modeling free surface flows, and it has become an alternative to traditional mesh-based methods for modeling waves. Owing to the Lagrangian nature of the mesh-free method, there is no need to deal with the free surface when it is applied...

ABSTRACT An interface-preserving level-set numerical method has been incorporated into a Reynolds-Averaged Navier-Stokes (RANS) method for the simulation of wave runup and greenwater effect on offshore structures. In this method, the free surface flows are modeled as immiscible air-water two...
